Orbital Contraction of Post-Common-Envelope Binaries with a Circumbinary Disk
Shigeyuki Karino, Kenji Nakamura
Tight and compact binary systems, such as double neutron star binaries, are believed to undergo a common envelope evolution phase, resulting in strongly bound orbits. During this p…
Characteristics and evolution of Be-type high mass X-ray binaries as potential Ultraluminous X-ray Sources
Shigeyuki Karino
Some ultraluminous X-ray sources (ULXs) exhibit X-ray pulses, and their central sources are thought to be neutron stars. It has also been suggested that some are transient sources…
Bimodality of Wind-fed Accretion in High Mass X-ray Binaries
S. Karino
We study an influence of X-ray photo-ionization from an accreting neutron star in a high mass X-ray binary. Our aim is to unveil a new principle governing X-ray luminosities of X-r…
Orbital parameters of supergiant fast X-ray transients
Shigeyuki Karino
Supergiant fast X-ray transient (SFXT) is a new class of the high mass X-ray binary that shows short X-ray flares. The physical mechanism of SFXT short flares is still open for dis…
